Miis will work in Guitar Hero 5

Activision has said that Miis, like Xbox Live Avatars, will be supported in Guitar Hero 5.

Support for PS3 Home Avatars, on the other hand, is unlikely.

"While there are no plans to have Home Avatars for the PS3 version, the US has confirmed that Wii owners will be able to rock out with their Miis in Mii Freestyle Mode," a spokesperson for the publisher told us.
